There is an advantage to your solution rl.d.
The case is very well supported on the back of the cartridge against the printer's wall.
This minimizes the tilt with cantilevered weight.
The polycarbonate shell maintains its shape much better than PLA and ABS under pressure also.

I still like the various cartridge mods depending on what I am doing.
I still need to remain mobile with my printers so KISS carts are viable solutions.

I think you have overcome the biggest challenge for trying to print something similar.
Using an element designed for the job.

Thanks. I am covered for my needs.
I never really wanted to make filament boats but now I have 2.
Holding stock spools is working well for me on the clamp.

However, there may be others interested.

As I've said from the very beginning of the hub projects;
There is significant functionality in the original cartridges that is useful and probably needed.
Their only weakness is the size and the latches.
Latches can be replaced with a simple clamp and the rest of the cartridges is still completely functional.

To me, KISS carts are still the best portable solution. They are more compact when you remove the tube.
They are robust; they are reliable; they are refillable. Only downside is the chip being dedicated to the cart.

one improvement I can see on the tube is to make it removable... like a pocket to slide the tube into.
You can bolt the seat on the cartridge and simply slide the tube in, similar to a tripod camera mount without the latch.
This would compact the solution for storage or transport.

i'm agree that kiss method is good solution.
i try several, but my pla is empty, i want to print with abs with 1cm brim,
i know you cannot share your stl, but can you help me so i can try with my abs? or share with other format
thanks dee

may i try with stand holder to ground, to make support for 1kg filament or above
thanks

wow, i'm very pleasant, thank you very much Dee, i hope no to bother you,

my setting abs left side, other setting as original first you share, no sidewalk n support (support use with object you manual create) , just add manual brim object with 1cm width dan 0.2mm height (that ussualy i use for abs with blue tape and white glue solution for bed adhesive)

clamp i use m6, can you make with m10 too? may i try with new de-spooler?

thank you Dee
last i try this kiss method with my last pla, its worked great, i print with 14hours successfull,
just i want to mod with iron clip (as original cattrige) at diy_hub,

Are you using LokBuild or stock plate? The de-spooler will run into the cube logo on the plate.
Won't bother the print, but just so you know. Fill with white glue may help.
There is an orientation for the small holes I am preserving.
I didn't want to shove the part all the way over to the edge.
The brim limits my positioning.

As for M10, that will require an adapter. Enjoy making one if you really want one
At some point I have to limit the scope.
